The Tecumseh step test is an exercise test that researchers use to determine a person's cardiovascular fitness level.. The Tecumseh step test is a modified version of the Harvard Step Test, [1] and was developed by Professor Henry J. Montoye at the Department of Epidemiology, School of Public Health, University of Michigan.
A normal minute volume while resting is about 5–8 liters per minute in humans. [1] Minute volume generally decreases when at rest, and increases with exercise. For example, during light activities minute volume may be around 12 litres. Riding a bicycle increases minute ventilation by a factor of 2 to 4 depending on the level of exercise involved.
The test subject repeatedly steps onto and off of a platform every two seconds. [2] The height of the platform is 20 inches or 51 centimetres for men and 16 inches or 41 centimetres for women. The rate of 30 steps per minute must be sustained for five minutes or until exhaustion. To ensure the right speed, a metronome is used.
Minute ventilation is equivalent to tidal volume multiplied by respiratory rate and is used to assess metabolic activity. Peak inspiratory flow (PifVt) is a measure that reflects respiratory drive, the higher its value, the greater the respiratory drive in the presence of coordinated thoraco-abdominal or even moderately discoordinated thoraco ...
Impulse oscillometry (IOS), also known as respiratory oscillometry, forced oscillatory technique (FOT), or just oscillometry, is a non-invasive lung function test that measures the mechanical properties of the respiratory system, particularly the upper and intrathoracic airways, lung tissue and chest wall, usually during the patient's tidal breathing (the way someone breathes when they are ...
Before starting the Heimlich, check to make sure the person isn't breathing, talking or coughing, experts advise. In any choking emergency, Mass General Brigham suggests first calling 911 to ...
[1] As the intensity level of the activity being performed increases, breathing becomes faster; more steadily first and then more rapid as the intensity increases. When breathing surpasses normal ventilation rate, one has reached ventilatory threshold. For most people this threshold lies at exercise intensities between 50% and 75% of VO 2 max ...
